partnership Application September 19, 1946, Serial No. 697,965

This invention relates to truck bodies for haul ing and dumping materials, such asconcrete, or other gravity displaceable materials, as sand and gravel, and particularly to bodies which are adapted to dump the concrete or other materials at one side of the truck as into a row of small molds or a trench, or to form an elongated pile, and which require that discharge be well beyond the wheels of the truck, and at some height above the ground level.

The invention has particular application to a body for transporting and delivering concrete into rather shallow elongated molds, such as would be required for fence posts, or molds for concrete blocks or slabs of the type used in levee control work in which the finishing product is a group of blocks closely assembled sideby side and linked together into a more or less flexible mat, and in which the mat width requires discharge reach and itslength requires an extended locus of discharge. In this work also it is often advantageous to fill one set of molds, cover them, place an additional set of molds thereon and repeat the operation several times, establishing eventually a discharge point of considerable height, requiring a corresponding height of discharge. i

The objects of the present invention are:

To provide a body which will discharge. its content laterally and without the necessity of backing the truck into discharge position;

To provide content laterally and spread the discharge along a path of considerable length;

To provide a body in which a substantial height of discharge level is maintained;

' To provide means by which the discharge rate may be controlled and continuously regulated or varied as discharge progresses.

In accomplishing these objects I provide a dump body having a laterally extending chute or nozzle disposed near the hinge center about which the body is raised, so that when the body is in dump position the height of the chute above the ground will not be lowered appreciably, since the eccentricity of the chute to the hinge center is small; and an arcuate transverse member incorporated within the truck body which is positioned to deflect all of the material to be emptied from the truck toward the back at one side and to afford a substantial thrust while it is being discharged.

I further provide a means of governing the rate of flow of the material being discharged a body which will discharge its.

r 6 Claims. (01. 298-18) by a gate, under control of a workman durin such discharge.

The means by which the foregoing and other objects are accomplished and the manner of their accomplishment will readily be understood from the following specification upon reference to the accompanying drawings, in which:

Fig. 1 is a side elevation of a dump body truck embodying my invention, with the body in dumping position.

Fig. 2 is a plan view of the truck body.

Fig. 3 is a sectional side elevation of the body taken on the line III-I[I of Fig. 2. I

Fig. 4 is a fragmentary end elevation of a portion of the truck body and the chute extending laterally therefrom.

Fig. 5 is a rear end elevation of the truck with the body in the dumping position of Fig. l, and

the junction of the chute and body in section.

The .body may be adapted from an ordinary dump truck body of the usual rectangular shape, or be designed and built as an entirely new structure. If an old body is used it is usually advantageous to deepen the side and end walls of the body to compensate for the reduction in capacity.

The instant construction substantially shortens the efiective length of the body, and it is usually necessary to increase the depth of the body to preserve the capacity. With an old body this may be done by welding on plates which extend above the normal top of the body, such construction being shown in the drawings, but such extensions are not necessary unless an old body is made use of.

In the present description reference will not be further made to these extensions, and the parts shown but not used, will not necessarily be referred to.

Referring now to the drawings in 'which' the various parts are indicated by numerals:

II is a truck chassis and I3 the cab. Hinged to the chassis as by hinges I5 is a truck body l1 which. is raised into dumping position by .a

conventional hydraulic cylinder-piston assembly H), or otherwise as desired. J

The body is preferably of rectangular shape and comprises a bottom 2| which is supported by longitudinal beams 23 to which are attached brackets I 5A forming part ofthe hinge, these brackets being adjacent the rear end of beams and body.

From the bottom 2| a front wall 25 and side walls 21 and 29 extend upward in usual manner. The body has a back wall 3i which extends the chute 35 is secured to the side wall around the Y aperture and extends laterally outward well beyond the wheels of the truck, as to dump into forms 35, disposed along the said side of the truck, this chute preferably tapermg from the opening in the side wall conically to a discharge end 35A which carries a closure gate 31. The gate 3'! is supported at its upper edges by hinges 39 and is provided with a latch pin 4! and complementary latch 43 by which it may be held closed.

Adjacent the lower side of the gate 3! is a socket 45 which is adapted to snugly receive the end of a removable handle a1 through which the amount of opening of the gate may be manually controlled, the handle beingmade removable be cause its extension, when in place, would neces sarily interfere with the movement of the truck from the mixer to the place of discharge.

The bottom 35B of the discharge chute at its connection to the body is substantially tangent to the arcuate back 31 and the chute bottom-may slope slightly downward from the horizontal as it extends outward from the body. The back 35C of, the chute extends outwardly and rearwardly fromthe body at a small angle.

In use, the concrete is put into the body and transported to the work. The truck is driven alongside the work and the body tilted to dump position and if desired the gate unlatched and discharge made of the entire load in a pile. The gate may, however, be unlatched and controlled by the lever and the truck driven along side the work discharging at such rate as is desired or necessary to fill successive molds as they are reached. In discharging the back and top of the body converge the concrete toward and through the chute.

It will be understood thatthe trucks are not intended for general highway use and that the chute extension weight interferes with transfer from place to place.

The chutes are, therefore, preferably connected to. the bodies by bolts so that disconnection and replacement may be made when and if it becomes necessary. Preferably all other connections are made by welding.
